.ASSIGNOR TO PACKARD MOTOR CAR COH- A'.EANY, OF DETROIT, MICHIGAN, OORPORATION 0F MICHIGAN v SPRING' COVER f Anuman mea 0mm ze, 192s. sum1 no. 315,158.

This invention relates to motor vehicles and more particularly to covers for the springs thereof. u

An object of the invention is to rovlde a for the protection of t e sprlng from dust, mud,'water and other-extraneous material which would have an injurious eiect thereon.

Another object of the invention is to rospring cover adapted to retain lu ricants within and between the portions of the springs which slide or move one on another.

Another object ofthe invention is to provide a sectional spring cover designed to permit unrestricted movement of the spring.

Yet another object of the invention 1s to provide a spring cover having a lining removable with the cover.

A further object of the invention is to pro'- vide a sectional spring cover having a separate lining for each section arranged to telescope with one of the adjacent sections.v

A further object of the invention is to provide a sectional metallic spring cover having a lining permanently secured to the inner wall of each section and provided with means whereby the cover may be easily and quickly ap lied or removed.

till a further object of the invention is to provide a sectional metallic spring cover which is highly eicient in operation and yet of marked simplicity as a whole and in respect to eachvof its component parts, so that its manufacture may be economically facilitated both as to parts and their assembly.

Other objects of the invention will appear from the following description taken in connection with the drawings, which form a part of this specification, and in which:

Fig. 1 is a side elevation of a half elliptic spring illustrating the invention as applied;

Fig. 2. is an enlarged side elevation of al spring with the cover applied, the cover'beand a portion oflthe Fig. 3 is an enlarged top plan view of the spring with the cover applied, the cover being shown 1n section, and a part of the Lspring being broken away;

Fig. 4 is a cross sectional view substantially on line 4-4 of Fig. 2;

Fig. 5 is a top plan view illustrating a modified form of the invention, and

'Fi 6 is a cross sectional view ofthe modified orm.

Referring to theA drawing for more specific details of the invention, 10 represents generally a leaf spring of the type well'known in the art as a semi-elliptic spring. The spring shown is built up from a main or master leaf 11 provided at its ends with eyes 12 and a series of `super-imposed leaves 13 and 14 arranged aboveand below the master leaf and secured thereto and to each other by a center bolt 15.

Positioned on the spring on each side of the center bolt is a pluralityof sleeves or jackets 16. As shown, the jackets are in graduated sizes, each graduallyl decreasing in cross section so that when adjusted to the spring the assembly conforms substantially to the general contour of the spring, when in an unsprung position. The jackets which are formed from thin sheet metal are longitudinally split so that they may be clippedl over the spring and the split edges are turned outwardly to provide flanges 17v in'which are positioned transverse bolts 18 for securing the jackets on the spring.

The ackets 16 are provided with linings 19, pre erably waterproofed felt. As shown, the linings are cut and shaped to conform to the jackets and the ianges thereon, and are secured in the jackets by rivets 20, though they may be cemente or otherwise secured in position. They are relatively thick and are positioned in the jackets so that one end of a 'lining is spaced from the adjacent end of the jacket in which it is secured as indicated at 21 and the opposite end extends outwardly beyond the jacket as indicated at 22. The waterproofing isy indicated at19.

The jackets are arranged on the spring in I j riveted to the two parts as at 26 to provide a suitable hinge. 'lhe fabric 25 not onlyprovides a hinge whereby the jacket maybe easily and quickly removed from the spring together with its lining, but serves to seal the joint between the two parts ont the acket.

Although the invention yhas been described in connection with certain speciic embodiments, the principles involved are susceptible of numerous other applications thatwill readily occur to persons skilled lin the art.

. The invention lis therefore to be limited only as indicated by the scope of the appended claims.

Having thus described the various features ot my invention, what l claim as new and desire to secure by Letters Patent is:

i. .fr spring cover comprising a metallic jacket, a lining secured in the jacket, said lining spaced from one end of the jacket and extending beyond the other end.

2. l spring cover comprising a plurality of jackets, each having a lining secured therein spaced from one end and extending beyond the other end, said jackets arranged in abutting relation with the lining in one telescoping with another,

3. A spring cover comprising a split metallic jacket having a gradually decreasing cross section anda lining secured to the jacket, the exterior of the lining being waterproof.

Il. A spring cover comprising metallic jackets arranged in abutting relation, y'each jacket being gradually reduced in cross section and split longitudinally, and a lining secured to each jacket, the exterior of the lining being waterproof.

5. A spring cover comprising metallic jackets arranged in abutting relation, a lining secured to the innerwall of each jacket, the linings being arranged to abut intermediate the ends of the jackets and means for securing the jackets on a spring.

6. A spring cove-r comprising detachable i metallic jackets arranged in abutting rela,-

tion, a lining for each jacket interconnected with one of the abutting jackets and means for detachably securing the jackets on a spring. I

- 7. A spring cover comprising metallic jackets of graduated sizes arranged in abutting relation and a lining in each jacket telescoping one' of the jackets immediately adjacent.

8. A sprin cover comprising metallic jackets of gra ually decreasingcross section,

said jackets beingin graduated sizes and arranged in abutting relation, a lining for each jacket adapted to telescope one of the adjacent jackets and mea-ns for detachably mounting the jackets on a spring.

9. A spring cover comprising metallic jackets of gradually decreasing cross section, the jackets being in graduated sizes arranged in abutting relation, a lining for each jacket adapted to telescope one-of the jackets immediately adjacent, means for securing the linings in the jackets and means for removably securing the jackets on a spring.

y10. A. spring cover comprising metallic jackets of gradually decreasing cross section arranged in abutting relation, a lining for cach jacket telescoping one of the jackets immediately adjacent and abutting the lining therein, means securing the linings to the jackets, means for fitting the lining' to a spring, and means providing for ready rcnioval and replacement ofthe jacket.

lLA. spring cover comprising a metallic jacket formed ot a plurality of longitudinally extending abutting sections each formed in two parts, and a lining secured to the parts of each section and forming a hinge therefor.

1 2. A spring cover comprising a metallic jacket formed of abutting sections, and a Water proof lining interior of the jacket sealing the joints between the sections.
